Block charter and jet card programs can be great options. Not only do they simplify the booking process, they also provide benefits, such as discounted fees and, on occasion, guaranteed airplane availability and upgrades.

Fortunately, rigorous pilot training and aircraft maintenance standards make such events few and far between. Even rarer is the case when a design flaw brings down a relatively new airplane.
